In truth, the results may cause you an enormous fats ticket or perhaps a felony cost. A poorly tuned electronic management unit can result in decreased performance, driveability, and should even trigger engine damage. In addition, altering gasoline maps to coincide with the stoichiometric ratio for gasoline combustion can also realize performance improve.
Remaps ought to all the time be carried out final, because the timing/fuelling and turbo durations will range relying on how well the engine can convert fuel into power. Adding simply an induction equipment or exhaust, gained’t have an effect on power a lot, you have to stability the flow of air through the engine.
Via the OBD communications protocol, electronically controlled features of the engine can be modified in a course of known as mapping. Mapping can both be carried out by altering the software inside the ECU (chip tuning via firmware modification), or by providing false data by way of plug-in hardware.
All levels are fully appropriate with an upgraded intercooler, catback exhaust, or other minor bolt on modifications. Finally, each stage is offered with special “Low Torque” software, designed to restrict peak torque to be used with an unmodified factory handbook clutch. Another cause to alter the digital management unit map is if there are engine, intake, or exhaust modifications to the automotive.
Here at Auto Express we receive loads of emails asking advice about ECU software program adjustments, and we have compiled this information to discover the pros, cons and prices. … Read More
